    摘要: The present invention relates to an opaque, white UV-resistant low-flammability film with a thickness of from 10 to 500 &mgr;m whose principal constituent is a crystallizable thermoplastic. It also comprises at least barium sulfate, at least one UV stabilizer and at least one optical brightener. The barium sulfate and/or the optical brightener and/or the UV stabilizer here is either incorporated directly into the thermoplastic when the polymer is prepared or fed as a masterbatch during film production. The novel film is particularly suitable for interior decoration, for constructing exhibition stands, for exhibition requisites, for displays, for placards, for labels, for protective glazing of machines or of vehicles, in the lighting sector, in the fitting out of shops or of stores, as a promotional requisite or a laminating material, or in applications associated with food or drink, and also for outdoor applications, such as roofing systems, external cladding, protective coverings, applications in the construction sector, or illuminated advertising profiles, or in the transport sector.

    摘要: The present invention relates to a transparent, low-flammability, UV-resistant, oriented film made from a crystallizable thermoplastic and having a thickness of from 5 to 300 μm. The film comprises at least one UV stabilizer and at least one flame retardant, and at least the flame retardant, and preferably also the UV stabilizer, is fed directly as a masterbatch to the crystallizable thermoplastic during production of the film. The film may have one or more layers, and the UV stabilizer may have been selected from the group consisting of the 2-hydroxybenzophenones, the 2-hydroxybenzotriazoles, the organonickel compounds, the salicylic esters, the cinnamic ester derivatives, the resorcinol monobenzoates, the oxanilides, the hydroxybenzoic esters, the sterically hindered amines and triazines, and the flame retardant may be an organic phosphorus compound, in particular an organic phosphorus compound soluble in polyethylene terephthalate.
